Comment 30 for bug 1322302

The ability to specify a different image stream to allow daily images to be used query simpleastreams images was added in 1.17.2, but this was for cloud nodes started by the provider directly in the cloud, not images fetched by uvt-simplestreams-libvirt as is done when creating a kvm container.

We can extend the kvm provisioning component of Juju to also honour the "image-stream" configuration setting.

Additionally, there is now also agreement that we are to introduce configuration settings to disable apt update/upgrade steps at bootstrap, reducing provisioning time even further.
